Definitions

  • polyolefin and polyester grids are low modulus of elasticity materials typically having Young's moduli on the order of about 10,000 to about 75,000 psi for polyolefin grids and from about 75,000 to about 200,000 psi for polyester grids.
  • Such low modulus products display high strain when subjected to the stresses in typical earthen structures.
  • overlying soil and other forces associated with or imposed upon the earthen structure may induce as much as twelve inches of strain in polyolefin grids directions substantially transverse to the face of the earthen structure. Strains of this magnitude may destabilize not only the soil structure itself but also nearby structures such as buildings or roadways directly or indirectly supported by the soil structure.
  • FIG. 5A and 5B sequentially depict installation of the geotextile fabric of FIG. 4.
  • the weft strands 26 are preferably stitched or otherwise loosely connected to one another via chain loops, tricot loops or the like, with tough yet supple thread or yarn such as 70 to 2000 denier polyester yarn or the like.
  • the openings established by weft and warp strands 26, 28 preferably range from about 3 ⁇ " to 1" on a side, though openings ranging from about V ⁇ " to six inches on a side may be used.
  • Strands 26, 28 may be united using warp-knit, weft-insertion knitting apparatus or other conventional weaving equipment.
  • the grid should preferably have a minimum strength of 10 kiloNewtons per meter (kN/m) in the direction of the weft strands 26, more preferably at least 50 kN/m and up to about 100 kN/m or more.
